Glen Oliver Lane and the fate of his small reconnaissance team still haunt me to this day. We never met. Our paths crossed only momentarily 47 years ago.

On May 20, 1968, me and two two other young, green Green Berets entered year four of the top-secret war that was fought during the Vietnam War. It was fought for eight years under the aegis of the Military Assistance Command Vietnam–Studies and Observations Group, or simply SOG.

The three of us had completed our in-country training in Nha Trang, South Vietnam. We received our top secret SOG briefing in Da Nang, which included signing government documents vowing not to discuss, write about, or photograph any aspect of SOG’s mission for 20 years. We were told that if we violated that agreement, we would be prosecuted to the fullest extent of the law and that we were to tell no one, parents, girlfriends, lovers, or friends about SOG.

On the morning of May 20, the South Vietnamese Air Force’s 219th Special Operations Squadron flew us north from Da Nang to FOB 1 in Phu Bai, located 10 miles south of Hue. The three of us exited the H-34 Sikorsky helicopter as a recon team—codenamed ST Idaho—boarded the nine-cylinder warbird, and headed west into one of the deadliest SOG target areas: the A Shau Valley.

Because the helicopter crew chief told us to hurriedly exit the chopper, we didn’t pay much attention to the six men from ST Idaho who boarded it and headed west toward Laos and the A Shau Valley. Since 1965, three Green Beret A-Camps were driven from the valley by communist North Vietnam Army troops, as it was a vital artery where enemy soldiers and supplies from the north flowed into South Vietnam.

Had I been more observant, I would have seen the team leader, codenamed One-Zero, Glen Oliver Lane; his assistant team leader, codenamed One-One, Robert Duval Owen; and four tough, fearless South Vietnamese indigenous troops climb aboard the chopper through its only passenger door on the right side of the helicopter.

Since there was so much enemy activity in the A Shau Valley and down the Ho Chi Minh Trail, ST Idaho’s mission was to find out what the enemy was up to and if any more future attacks were being planned—such as the Tet Offensive earlier in the year, where communist forces struck in surprise attacks across South Vietnam during the national holiday of Tet.

Shortly after I entered FOB 1, I met Staff Sgt. Robert J. “Spider” Parks, whom I first encountered while I was going through Special Forces Training Group in 1967. Spider explained that he was a member of ST Idaho, but he was unable to go on this mission, hence he was nervous about the safety and well being of his team.
